SIGN-LETTER.

Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed August 16, 1909. Serial No. 513,049.

To all whom it may concern: Be it known thatI, JOHN MRAZEK, a citizen ofthe United States residing at Chi cago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inSign-Letters, of which the ollowing is a specification.

My invention relates to improvements in sign letters, the main object ofthe invention being to provide suitable means for securing transparentornamental inlays in a letter of this character.

A further object of my invention is to i provide adequate means forprotecting the inlays from the weather when the same are silvered toform mirrors thereof.

Other objects will appear hereinafter.

With these objects in view my invention consists in the novelconstruction and arrangement of parts which will be hereinafterfully'described and more particularly pointed out in'the appendedclaims.

My invention will be more readily understood by reference to theaccompanying drawing forming a part 6f this specification,

'and in which,

Fi re 1 is a front elevation of my improved sign letter, showing thesame attached to a sign board, Fig. 2 is a transverse section takenthrough the letter and one of the'ornamental inlays secured'therein,Fig. 3 1s a section similar to Fig. 2 but showing an inlay in elevation,and Fig. 4 is a transverse section showing a recess or depression inwhich an inlay is secured.

Referring now to the drawings, 1 designates a sign board and 2 a letterof my improved construction attached thereto. Formed in the letter 2 area plurality of hemispherical recesses or cavities 3 as shown in Flg. 4.Substantially hemispherical transparent ornamental inlays 5 are pro-.vided, the same having preferably a series of facets 6 cut on thecurved portions there-, of. These facets are silvered in order that eachinlay may produce a brilliant effect by reflecting light.-

In order to secure each inlay 5 in its re cess 3, the recess is firstpartially filled with 60 cement 7 'in a plastic condition, then theinlay is forced therein until it becomes on a level with the surface ofthe letter. The

secured therein.

cement is smoothed ofi' flush with the sur face of'the inlay and theletter, and when the same becomes set the inlay is rigidly Owing to theadherence of the cement 7 to the silvered portion 8, the latter will notbe affected by the weather, consequently the facets will always'reflectlight perfectly and present a brilliant and dazzling appearance.

The letters are formed preferably of wood butany other material whichthe cementwill readily adhere to may be employed. The inlays may becolored lass, cut crystal, or other like substances. W sired to producea color effect the letters may be colored or tinted, and the inlays beformed of colored glass to match the color of the letter. .The facets ofthe inlaysare preferabl cut or ground but may be molded in the size anthe design of the facets may be varied to suit the taste or anyparticular design of letter.

Various changes might be made in the general form and arrangement ofparts described without de arting from my invention, and hence I db notrestrict myself to the precise details set forth, but consider myself atliberty to make such changes and alterations as fairly fall within thespirit and scope of the a pended claims.

Having describe my invention what I claim as new and desire to secure byLetters Patent is: 1. A sign letter comprising a body having recessestherein and, a transparent inlay havass, it being understood that thehere it is deing mirrored facets on its inner surface, the

sald inlay being embedded in and having its mirrored facets completelycovered by ce-' ment, substantially as described.

2. A'sign letter having a series of hemispherical recesses formedtherein, a layer of cement in each of said depressions, and asubstantially hemispherical transparent inlay having facets formed onits substantially curved surface secured in each recess, thefacets beingsilvered to form mirrors of said inlays, substantially as described.

3, A wood sign letter having a plurality of hemispherical recessesformed therein, a layerof cement in each recess, a substantiallyhemispherical transparent inlay secured in the cemen t of each recesurface of each inlay, said vered and adjacen each recess, substan t thelayer 0 ss, the layer f a-unlform ut 1n curved.

facets being sil f cement in i tially as described. 1 In testimonywhereof I have signed my 1- na1ne to this specification in the presenceof two subscribing Witnesses.
